Blimey this rolled onto page 2 so I thought I'd best do an update
Progress is actually quite slow, despite my best efforts as I'm getting into the 'fiddly bits' area where one thing is dependant upon another which is dependant upon something else. Biggest one currently is that I'm having to do one thing then remove all the masking tape and apply it in a different layout to do the next as we all agree, masking things off does take as much time as painting. It is starting to come together though so overall I'm quite happy.
The first part of the red strips has been finished, I did have a tiny bit of overspray where the edge of the next panel caught some red underneath the masking tape (the rivets pushed the tape up) and I've a little bit of brush work where the masking tape managed to edge over rivets that would be fully red. I'm planing on having a small line of red between the two strips (positioned just behind the front strip) to add a bit of interest and break up the plain beige effect.
I've airbrush black'd the exhausts by hand which has created a "soot" effect round them which I'm going to leave. There just wasn't enough gap for even the thinnest bit of plasti-card behind them and they're going to be heavily weathered so it should work out quite well.
You might be able to spot that I've started to black out the aquila by hand. Bit of a boring job really but gold really benefits from a dark base colour. Thinking about it, it might be better to mask off the aquila's as best I can and airbrush the black and gold on and then touch up the hull colour by hand... Hmm, might do that actually.
The rear flooring was originally going to be done dark steel with brass edging, however looking at it, trying to mask off the various tiny brass bits is going to me more trouble than it's worth, so I'm thinking of going to plain steel.
